  Hello there

  Congratulations on successfully finishing the challenge!

  Your project is absolutely amazing.

  Here are a few suggestions that can further enhance your project:

   

  HTML comes with a built-in form validation API that is widely supported by modern browsers. This API allows you to perform client-side form validation without the need to write complex regular expressions. Instead, you can leverage the HTML's built-in validation attributes and properties to handle form validation.

  The key steps to implement form validation using the HTML validation API and JavaScript are as follows:

  Add Validation Attributes to the Form and Input Fields :

  • Add the noValidate attribute to the <form> element to disable the browser's default form validation behavior.
  • Add the required attribute to the input fields that should be mandatory.
  • Specify the appropriate type attribute for the input fields (e.g., type="email" for email fields) to enable built-in validation for the specific input type.

  <form action="" noValidate>
    <input
      type="email"
      required
      id="email"
      placeholder="[email protected]"
    />
  </form>
  

  Handle Form Submission with JavaScript :

  • Add an event listener to the submit event of the form.
  • Inside the event listener, call the preventDefault() method to prevent the default form submission behavior.
  • Check the validity of the form fields using the validity property, which provides various sub-properties like valueMissing and typeMismatch.
  • Based on the validity state, you can display appropriate error messages or perform other actions.

  const form = document.querySelector('form');
  const email = document.getElementById('email');form.addEventListener('submit', (e) => {
    e.preventDefault();  if (email.validity.valueMissing) {
      // Display "Please fill out this field" error
    } else if (email.validity.typeMismatch) {
      // Display "Please enter a valid email address" error
    } else {
      // Form is valid, proceed with submission
    }
  });
  

  Hope you found that helpful

  Keep up the hard work
